as a real-image.  The center of the filter mask lies in the center
of the resulting image.  The parameter <a href="#Scale"><i><code><span data-if="hdevelop" style="display:inline">Scale</span><span data-if="c" style="display:none">Scale</span><span data-if="cpp" style="display:none">Scale</span><span data-if="com" style="display:none">Scale</span><span data-if="dotnet" style="display:none">scale</span><span data-if="python" style="display:none">scale</span></code></i></a> determines by
which amount the values of the filter mask are multiplied (this
results in larger values of the Fourier transform of the filter).
The corresponding filter matrix, which is given in
<a href="#FilterMask"><i><code><span data-if="hdevelop" style="display:inline">FilterMask</span><span data-if="c" style="display:none">FilterMask</span><span data-if="cpp" style="display:none">FilterMask</span><span data-if="com" style="display:none">FilterMask</span><span data-if="dotnet" style="display:none">filterMask</span><span data-if="python" style="display:none">filter_mask</span></code></i></a> can be generated either from a file or a
tuple. The format of the filter matrix is described with the
operator <a href="convol_image.html"><code><span data-if="hdevelop" style="display:inline">convol_image</span><span data-if="c" style="display:none">convol_image</span><span data-if="cpp" style="display:none">ConvolImage</span><span data-if="com" style="display:none">ConvolImage</span><span data-if="dotnet" style="display:none">ConvolImage</span><span data-if="python" style="display:none">convol_image</span></code></a>.  Example filter masks can be found in
the directory “filter” in the HALCON home directory.  This
operator is useful for visualizing the frequency response of filter
masks (by applying a Fourier transform to the result image of this
operator).</p>
